A ship discovered off the coast of North Carolina in 1997 has been identified by experts as the Queen Anne's Revenge, a ship used by the pirate Blackbeard. The ship was originally named Le Concorde before the pirate seized it from its French crew in 1717. Artifacts, such as this apothecary weight featuring two fleurs-de-lis, helped to identify the ship as Blackbeard's.

Le Concorde's surgeon, who was forced to serve briefly in Blackbeard's crew, may have owned the weights, designed for pharmaceuticals. Pirates could have also used the weights to measure gold dust, experts say.
